请问谁能看明白这段代码 java的

m_nNodes=2;public boolean hasCycles() {boolean[] bDone = new boolean[m_nNodes];for (int iNode = 0;iNode <m_nNodes;iNode++) {boolean bFound = false;for (int iNode2 = 0;!bFound &&iNode2 <m_nNodes;iNode2++) {if (!bDone[iNode2]) {boolean bHasNoParents = true;for (int iParent = 0;iParent <m_nNodes;iParent++) {if (m_bits[iParent + iNode2 * m_nNodes] &&!bDone[iParent]) {bHasNoParents = false;}}if (bHasNoParents) {bDone[iNode2] = true;bFound = true;}}}if (!bFound) {return true;}}return false;} 收起
